1. Chicago Med

Tuesday, 9 p.m., NBC

Fans of “The Affair” know Colin Donnell as Scotty Lockhart, the felonious younger brother of Cole Lockhart (Joshua Jackson), whose murder is still unsolved. Donnell, 33, still appears in flashbacks, but this week he makes his debut on “Chicago Med.” The actor moved to Chicago with his wife, actress Patti Murin, to play Connor Rhodes, a surgical rock star who treats the most dire cases.
He spoke to The Post on a production break.

How were you cast on “Chicago Med”?
I’ve been up for a couple of roles on “Chicago Fire” and “Chicago P.D.” and I was on their radar. I don’t know many actors who get a call from a Dick Wolf production and say “no.” I’ve never been on a medical drama, and looking back at all the people who had a big break with medical dramas …

… You had visions of Clooney dancing in your head?
And [from “ER”] also Maura Tierney, Laura Innes, Noah Wyle.

Have you ever been told you look like Jon Hamm’s younger brother?

I’ve gotten it a few times. Believe me, I’ll take it. I met him when I was doing “Anything Goes” on Broadway. My wife and I went to dinner with Andrew Rannells and his boyfriend Mike Doyle. And Andrew invited Jon to join us. I tried to keep my cool, but I said, “I just love you.” I don’t think I embarrassed myself.

Scotty Lockhart won’t die on “The Affair.” What is that about?
This season is the end of Scotty Lockhart. It was a big surprise to me that he was getting episodes in Season 2. There’s some really cool stuff coming.

Is Cole going to become a suspect in Scotty’s murder?
There is maybe some shared culpability. As with much of the show, the truth is questionable. Things aren’t exactly cut and dried.
